M'IRALL and CHARLES Gi 'Anirsrrionc, citi Zens of the United States, and residents of This invention relates to furnaces, andparticularly'to that. class of furnaces ordiiiai'ily used for heating boilers.

The object of our invention is to provide 7 a furnace for heating steam boilers, and of such construction that it may also be used for incinerating garbage, without detract ing from its eifectiveness as a steaingenerat y ing plant. I

Another ObJGCt of our invent on is to provide means for automatically conveying to the incinerator ofthe furnace; garbage collected in different parts of the building or buildings, in connection with which the steam generatingand. incinerating plant is used.

A further object of ourinvention is to provide suitable suction-pressure"apparatus which, while acting as a garbage-conveying means is also utilized for supplying a forced draft to the furnace. 1

Other objects, such as economy of opera tion and installation will readily suggest themselves from a reading of the specifica= tion, in connection with the accompanying drawings, in which,

Figure 1 1s a vertical longitudinal section room in a building, having aportion of our conveying apparatus located therein, the other portion'being located in close proximity to the incinerating furnace placed in the basement. V 7

Referring to the construction illustrated: The furnace is represented in whole at .A, with part broken away, the front wall being represented at B, the back wallet 0, and a portion of the roof at D, having a iiue outlet D. Suitably mountedin recesses in the walls B and C is a water tube boiler, represented at E, which may be of any-of the well known forms, and the construction of which neednot be here specifically described. V vided av bridgewall F, which divides the furnace A transversely into two compart- Ii iidway of the furnace .is pro- 7 n'ents, the front compartment G, and the "rear compartment H. wardly from the top of thelfurnace is a baliie E" for deflecting'the gases from" the front compartment into the rear compartpe fic ti nz i s e Eateiited Dec. 15,1,914.- Application filed lune l 'liilfi.

Extending downment on their passage to the flue-outlet D.

The front compartment G, which is the primary heating or fuel-burning chamber of the furnace, is provided with theusual fire grate" G, andlthe fire grate opening G having the door The lower portion of the chamber G is provided with the ash-pit floor G and the ash-pit openingG having the ash-pit door G.

The rear compartment secondary or, garbage-burning chamber of the furnace, is provided with a grate bar Hf, a garbage receiving opening Ila-and a" door therefor H It isalso provided with the ash-pit fioorH an o enin communia P an eating therewith H and a' door H closing .saidyopening.

, k H, which isthe Extending transversely. of the furnace is i a conduit I, having an air flue therein "rep resented at I",'wliich fluegmay communicate with the 'e kteriorlatinosphere in any suitable manner, andmay also be connected to a source offorcedidraftias hereinafter described. Communicating at J' with'the air flue Iyand at K'with the lower portion of the chamber G, is an air flue LL Also conipo'rtionofithe chamber H is anlair flue M.

The opening Kof the flue L is provided with .a flue damper N adapted to close said opening by means of the rod N, having a handle N which .rod projects through a suitable opening throughthefront wall of the furnace. The opening J of the flue L is provided with afiue damperO, which may be connected to or forined'integral with one arm of a ball crank lever P, which is pivot-' having the handle or foot-tread It, located adjacent to the front of-the furnace. The

other end'of therod P is formed with across-bar S, which is adapted to have limit ed movement within a movable guideway 'municating with the' fiue I" and the lower S, one end of Which is suitably mounted in the air flue M, and the other end of which is provided with flanged portions S which are adapted to contact with the cross-bar S, and on such contact when motion is imparted to the guideway S toward the outer end of the flue M, motion is imparted to the cross-bar S in the same direction, and when motion is imparted to the cross-bar S in the opposite direction, motion is imparted to, the guideway S.

The air flue M is provided with a flue I damper T, which at one side is connected the furnace and vice versa, and for this purpose 'we have shown a signal bell U,

- located at thefrontof the furnace, operated by the wire U, and the wire-pull U at the rear of the furnace.

The rear side of the furnace is provided vith a signal bell V, operated by the wire V, and wire-pull"V ,;locatedat the front of the furnace, the purpose being thatwhen the operator at the rear of the furnace is about to charge the incinerator, he shall notify the engineer at the front of thefurnace, so that the latter may close'thefront doors and dampers, and signal that he'has done so, before the garbage charging door =H is opened, and thereby avoid the possibility of emission of heat and flame through the latter and injury to the operator. v

As thus far described the operation of our apparatus is as follows: Assuming that a coal fire is burning on the grate G in the chamber G the products of combustion will rise and, coming in contact with the tubes of the water-tube boiler E, will, owing to the construction of the latter, not only circulate upward and between said tubes, but

a large portion of the same will be deflected over the upper portion of the bridge wall F, and downwardly into the chamber H. Further assuming that a quantity of garbage has just been placed upon the gratebar H, and that the same contains more or less moisture, the latter will be" very quickly and thoroughly dried by the ordinary heat in the chamber H. lVhen such garbage has been subjected to the drying process in said chamber the operator will open the air flue M, closing the air flue L, and permitting a draft of air to come in contact with the garbage ant. gases of combustion passing over the bridge wall F from the chamber G,

whereupon the dry garbage will immediately kindle and be incinerated.

It will be observed that by our construction of furnace the air flue M may be closed from either the coal burning or garbageburningside of the furnace, but owing to the peculiar construction of the dampers the air from the flue I cannot be admitted to 7 both sides of the furnace at the same time, i and that when the damper T of the fine M .isclosed a draft of air may be admitted from the flue I, and through the flue L to the under side of the grate G, but this cannot be done when the air line M is open.

Referring now to the garbage-conveying portion of the apparatus, it consists of a closed receiver 1, having an outlet portion 2, within the inner end of which is hingedly mounted a swinging door 3, provided with a projecting arm 4:, having a weighted handle 5, which latter normally .-tends to keen the door 3 closed. Suitably mounted relative to the receiver 1 is a blower 6 of any of the; well known forms of construction, which is adapted to be operated from any convenient source of power, but preferably by a motor as indicated at 7, provided with the belt 7*. The blower has an outlet portion 8, and an inlet or suction portion 9,

vthe latter being connected to one end ofa pipe 9, whose other end lies within the receiver 1. The outlet portion 8 of the blower is connected by means of a main 8 with the flue I, whereby a forced draft may be admitted to the grate at thefront of the furnace. :Also connected to the receiver 1 is a chute 10.,the free end of which is provided with a receiver or hopper portion 11, having a hinged'cover 12, the same being shown as placed within a recess in an ordinary kitchentable 13. The outlet 2 of the receiver 1, will be suitably located relative to the rear wall C, and garbage receiving door H of the furnace. WVithin the hopper 11 we provide a hollow metal ring 14:, provided with a plurality of small openings 15, said ring being connected to one end of a steampipe 16, which'latter will be connected to any suitable source of steam supply. The steam-pipe 1G is provided with a valve 17, whereby steam may be admitted to or excluded from the ring-14L. It will be understood that kitchen refuse and other rubbish traveling through the chute 10, and the receiver 1, will soon coat the walls of the same with grease and dirt, and therefore we have made provision for the admission, through the small openings 15 of the ring 14, of fine jets of steam, whereby the same may be easily and quickly cleansed.

The operation of the garbage-conveying portion of the apparatus will be readily apparent: Operated by the motor '7, the blower 8 draws the air from the receiver 1, creating a vacuum therein, and also taking the air 1 from and creating a vacuum in the chute 10.

Vhile we have herein shown and described one particular embodiment and ap plication of our invention, we wish it to be understood that we do not confine ourselves to the details herein set forth, as modifica tion and variation may be made without departing from the spirit of the invention or the scope of the claims.
